Here's a link to the music files that trigger the bug (if relevant):
It happens with all files

Setup

• OS: Windows 10 Pro 22H2 19045.3570
• Python version: Python 3.9.0
• beets version: beets version 1.6.0 - no plugins loaded
• Turning off plugins made problem go away (yes/no): no

My configuration (output of beet config) is:

directory: D:\Music
library: D:\Music\musiclibrary.db

import:
    move: yes

Thanks for the report. Does it happen with the latest beets version as well? https://beets.readthedocs.io/en/latest/contributing.html#getting-the-source

Should be fixed in #4209. If not (i.e. if this error still occurs with the latest beets version, as pointed out by @JOJ0, please re-open this issue.)
